Shortest day in recorded in history

Earth Rotation Anomaly - Earth's rotation is experiencing a slight acceleration, resulting in days being shorter than the usual 24 hours (86,400 seconds) [1] - Some days this summer are milliseconds shorter than normal [1] - One day is expected to be approximately 1.3% milliseconds shorter than a typical day [1] Potential Causes - Tide effects from the moon and sun contribute to the change in Earth's rotation [2] - Changes in the Earth's fluid core influence the planet's rotation [2] - Weather phenomena are also a factor in the observed changes [2]
